Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field enerLD can be converted to heat enerLD in mudium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,mircrowave heating is achieved.

The principle of microwave sterilizing

Mircowave sterilizing is the result of combined action of the thermal effect of eletromgnetic fields and the biological effect.Thermal effect of microwave on the bacteria denatures the protein of bacteria ,and make the bacteria lost the condition of nutrition,reproduction and survival so as to die .The biological effects of microwave on the bacteria is that the microwave electric field changes the potential distribution of cross-section of the bacterial cell membrane and impacts the concentration of electron and lon around the membrane ,and changes the permeability of cell membranes ,therefore the bacterium become innutrient and lost normal metabolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,as a result they are dead.Moreover ,nucleic acid genetic(RNA) and deoxyribose acid (DNA),which decide the normal growth and stability of bacterial,are curly-shaped macromolecule made of a number of linked compactly hydrongen bond .The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome aberration and even rupture.

I. General Description

1. Dry temperature: adjustable

2. Type of Feeding: continuous

3. Type of Control: control panel

II. The Features of Design

1. Transmission System:

a. Speed of Conveying belt is adjustable.

In the transmission system, it applies frequency-converting control of speed, worm gear reducer.

b. The conveyor belt is Teflon Belt, special for microwave.

c. The deviation of belt is adjusted with Hand-movement.

2. The body of the Tunnel

a. The body of the microwave tunnel is made of Stainless Steel. In side there is one set of humidity extraction system to extract the humidity after heating.

b. To be safe, there is Automatic Power-off device while open the door of the machine.

c. The protecting case of Magnetic-pipe and transformer is made of stainless steel. On top there is one set of Heat extraction system to extract the heat enerLD generated by

working of machine.

d. The frame of machine is made of Stainless Steel pipe, others is made of cold-rolled sheet painted.

e. One set of infrared thermometric is installed at the outlet of the tunnel to measure the temperature.

Please note: Inlet/outlet orifice, conveyor belt size and overall dimension can be designed according to your requirements.
